The rebellion led to the dissolution of the East India Company in 1858. It also led the British to reorganize the army, the financial system and the administration in India. In August, by the Government of India Act 1858, the company was formally dissolved and its ruling powers over India were transferred to the British Crown. A new British government department, the India Office, was created to handle the governance of India, and its head, the Secretary of State for India, was entrusted with formulating Indian policy. The Governor-General of India gained a new title (Viceroy of India), and implemented the policies devised by the India Office.
